Title: Method of epitaxial growth at liquid phase
Inventor: FURUIKE SUSUMU
IPC: C30B19/10
Filed: 1979-02-28
Abstract: PURPOSE:To epitaxially grow layers of uniform thickness at liquid phase on the surfaces of plural semiconductor substrates, by placing separation walls of trapezoidal cross section between the substrates and changing the horizontal thickness of a solution surrounding each substrate, together with the depth of the solution. CONSTITUTION:A plurality of pairs of semiconductor substrates 1 placed back to back, are erected at a spacing on the substrate holding part 3 of a boat. Separation plates 4 of trapezoidal cross section are erected between the pairs of the substrates so that the major thickness ends of the separation plates are located as their tops or bottoms. A growing apparatus is thus constructed. The horizontal thickness of a growing solution 2 in contact with the surface of each substrate 1 is changed with the depth of the solution by the separation plates 4. As a result, the tendency to  thicken in the vertical direction due to the horizontal thickness of the solution 2 and  the tendency to thin in the vertical direction due to the concentration of the solution  2 cancel each other. Therefore, the thickness of grown layers becomes very uniform.

Filed: 1995-02-14
Abstract: PURPOSE: To detect breakage and leakage of water in a water-shielding sheet by mixing conductive fibrous material whose electrical resistivity is at most a specified value into fiber cloth for reinforcement and coating both sides of the fiber cloth for reinforcement with resin, and attaching terminals for checking continuity of conductive fiber to the fiber. CONSTITUTION: A water-shielding sheet is constituted by interweaving conductive fibrous material 1 of electrical resistivity <=2×10<-7> Ω.m with fiber cloth for reinforcement and coating both sides of the fiber cloth for reinforcement with a resin. Terminals 2 for checking continuity of the conductive fibrous material 1 are attached thereto in the water-shielding sheet. Breakage or leakage of water in the water-shielding sheet is detected by checking continuity of the conductive fibrous material 1. At this time, when electrical resistivity is high, the current hardly flows, and recognition of continuity is made difficult. For example, metals such as gold, aluminum, nickel and iron or alloy of copper and silver are preferable substance for forming the conductive fibrous material. Furthermore, elongation in rupture of conductive fiber is preferably larger than fiber for reinforcement excepting conductive fiber and smaller than the elongation in rupture of the water-shielding sheet.
